How to access a control inside DataGrid.RowDetailsTemplate?

Question

Following is my XAML:

<DataGrid.RowDetailsTemplate>
    <DataTemplate>
        <DataGrid Name="innerGrid" IsReadOnly="True" AutoGenerateColumns="False" Margin="10,10,5,5" Width="400" HorizontalAlignment="Left">
            <DataGrid.Columns>
                <DataGridTextColumn  Header="Ref" Binding="{Binding Id}"/>
                <DataGridTextColumn  Header="Investor" Binding="{Binding FundProvider.FullName}"/>
                <DataGridTextColumn  Header="Amount" Binding="{Binding InvestmentAmount}"/>
            </DataGrid.Columns>
        </DataGrid>                                                 
    </DataTemplate>
</DataGrid.RowDetailsTemplate>

My question is how do you access innerGrid DataGrid control from the code. Thanks in Advance.

Why do you want to access it in code? Your inner grid columns are data bound so bind `ItemsSource` of inner grid and process it in ViewModel — dkozl, Jul 13 '13 at 09:10
actually i want to make as a tree drop down when you click in the node. i want to add collapse and expand functions — Riyal MHH, Jul 13 '13 at 09:26

You can access inner DataGrid in LoadingRowDetails event (msdn).

private void outerGrid_LoadingRowDetails(object sender, DataGridRowDetailsEventArgs e)
{
    DataGrid innerGrid = e.DetailsElement as DataGrid;
    if (innerGrid != null)
    {

    }
}

Thanks kmatyaszek for the right answer. Previously I was trying with RowDetailsTemplate.LoadContent(), which was not updating the UI though able to get the objects.

Here is my updated sample code:

    void gridEmployee_LoadingRowDetails(object sender, DataGridRowDetailsEventArgs e)
    {
        Border border = e.DetailsElement as Border;

        if (border != null)
        {
            foreach (var grid in border.GetVisualChildren())
            {
                Grid grid_ = grid as Grid;

                if (grid_ != null)
                {
                    foreach (var textBlock in grid_.GetVisualChildren())
                    {
                        TextBlock textBlock_ = textBlock as TextBlock;

                        if (textBlock_ != null && textBlock_.Text == "City : ")
                        {
                            textBlock_.Text = "My assigned text...";
                        }
                    }
                }
            }
        }
    }
